Pesach

Why do we say "Come and learn what Lavan wanted to do to Yaakov Avinu, for Pharaoh only wanted to kill the boys, but Lavan wanted to uproot everyone"? All it does is trivialize the miracle of Yetzias Mitzraim! Its basically interjecting with "you know the guy Hashem saved us from wasn't really that bad". It just minimizes the miracle Hashem did for us! It doesn't add anything to the story either. We don't discuss Lavan at all. At the very least we should thank Hashem for saving us from him or something! It comes off almost rude. How is that a fitting introduction to Arami Oved Avi Vayered Mitzraimah"?
